Let F be the finite field GF(2n) of characteristic 2 and f a quadratic APN function on F. We construct a n(n−3)2 dimensional subspace Wf of F∧F, where F∧F is the alternative product of F, that is, the quotient space of the tensor product F⊗F

A new retrievable filter, consisting of a helical basket of ten stainless steel wires and a retrieval cable, was tested in 7 adult sheep. The filter was inserted into the infrarenal vena cava through a 9-F sheath and fixed subcutaneously by a stabili

We prospectively compared current digital subtraction angiography (DSA) with conventional film-screen angiography (FSA) of the lower limb for evaluation of areas of arterial stenosis and degree of arterial visualization. Fifty patients had both DSA a

The effects of two urokinase (UK) dose regimens on lysis time, lytic success, primary clinical success, and frequency of complications of peripheral thrombolysis were compared. Seventy-two intraarterial UK infusions were performed by means of standar

We proved affine planes corresponding to quadratic planar functions over $F_{p^n}$ are semifield planes, and we determined affine planes corresponding to planar functions $f(x) = x^10 − αx^6 − α^2x^2$ by Ding and Yuan. Moreover we calculated ex

The size of present rotational atherectomy devices is limited in part by a tendency to produce vessel torsion. The authors designed and investigated a large-bore rotational atherectomy device for peripheral atherectomy in a single pass without signif

We construct differentially 4-uniform functions over GF(2n) through Albert's finite commutative semifields, if nis even. The key observation there is that for some kwith 0 ≤ k≤ ni¾? 1, the function $f_{k}(x):=(x^{2^{k+1}}+x)/(x^{2}+x)$ is a two

Let $S$ be a blocking semioval in an arbitrary projective plane $\Pi$ of order 9 which meets some line in 8 points. According to Dover in $[2]$, $20\leq \vert S\vert\leq 24$. In $[8]$ one of the authors showed that if $\Pi$ is desarguesian, then $22\

It is shown that there is a relation between planar functions of elementary abelian groups and bent polynomials. Moreover we prove several results concerning them.
